What is a Colonoscopy?

A colonoscopy is a test that doctors use to look for and remove abnormalities in the colon or rectum, such as adenomas, polyps and inflammation of the colon. If left untreated, these growths may turn into colon or rectal cancer. A colonoscopy is key in the investigation of the colon and rectum and is also used to help doctors identify colon cancer. During the procedure, the entire colon and rectum are examined using a small, thin tube with an attached camera. This device is inserted into the rectum for observation.

Who needs one?

Everybody should undergo a complete colonoscopy by the time they turn 50. By this age, the overall risk of developing colorectal cancer increases and early detection is vital for effective treatment. In fact, bowel cancer is the most common internal cancer in South Africa and the second most common cause of cancer-related deaths.

How is a Colonoscopy performed?

Colonoscopy preparation is an important part of the colonoscopy procedure. Preparation is usually done at home, following directions given to you in our rooms.

The aim of colonoscopy preparation is to eliminate all faecal matter from the colon so that we can conduct the colonoscopy with a very clear view of the intestinal wall. You will be given oral laxatives two nights before your colonoscopy to start your bowel preparation.
